In order to restore uart context after entering
SYS_PM_DEEP_SLEEP, suspend and resume functions
are called.
The following parameters are restored:
- All registers for the UART device.
- UART clocks.
The FIFO control register cannot be read back and is
not stored in the device configuration.
The default parameters are applied for them.
The suspend/resume functionality is implemented in
the QMSI shim layer as a fast and temporary solution,
it will be removed and migrated to QMSI later.

In order to change the baudrate the DLAB bit of the LCR register has to
be set to 1 (This bit is used to enable reading and writing of the
divisor latch register). This bit must be cleared after the baudrate
setup in order to access other registers.
The set_baud_rate function correctly sets the DLAB bit of the LCR reg but
never clears it. Therefore the ns16550 doesn't properly work any more
after updating the initial baud rate.
In order to fix this issue the LCR reg has to be temporary saved
(because it contains other important settings). After switching to a new
baud rate the LCR reg value has to be restored.

This patch extends the UART QMSI driver so it supports the IRQ APIs from
include/uart.h. The IRQ APIs are enabled by the 'CONFIG_UART_INTERRUPT_
DRIVEN' option.
Differently from others APIs such as I2C and SPI, the UART API is very
low level. For that reason, the IRQ facilities (e.g. irq based transfers)
from the QMSI driver are not useful to the shim driver at the moment. In
order to implement the IRQ APIs we rely on UART registers defined by QMSI.
QMSI UART header is missing some macro definitions from IRR register so
we define them in the shim driver.
Since the IRQ trigger condition is not configurable in the QMSI shim
driver, this patch also changes drivers/serial/Kconfig so the "UART
IRQ Trigger Condition" choice doesn't appear on the menu if the QMSI
driver is selected.

This patch introduces the QMSI UART driver which is simply a shim driver
based on UART driver provided by QMSI BSP.
This initial version implements only the mandatory APIs 'poll_in',
'poll_out' and 'err_check' which are required by trivial sample apps and
by output functionality from the console driver. The remaining APIs will
be implemented by up coming patches. The driver supports only 115200 baud
rate at the moment.
In order to enable this driver, the following options should be set:
CONFIG_QMSI_DRIVERS=y
CONFIG_QMSI_INSTALL_PATH="/path/to/libqmsi/directory"
CONFIG_SERIAL=y
CONFIG_UART_QMSI=y
This driver has been tested with Quark SE Devboard so this patch also
adds its platform-specific default configuration options to 'arch/x86/
soc/quark_se/Kconfig'.

The peripherals utilizing UART were required to register their own
ISR rountines. This means that all those peripherals drivers need
to know which IRQ line is attached to a UART controller, and all
the other config values required to register a ISR. This causes
scalibility issue as every board and peripherals have to define
those values.
Another reason for this patch is to support virtual serial ports.
Virtual serial ports do not have physical interrupt lines to
attach, and thus would not work.
This patch adds a simple callback mechanism, which calls a function
when UART interrupts are triggered. The low level plumbing still needs
to be done by the peripheral drivers, as these drivers may need to
access low level capability of UART to function correctly. This simply
moves the interrupt setup into the UART drivers themselves. By doing
this, the peripheral drivers do not need to know all the config values
to properly setup the interrupts and attaching the ISR. One drawback
is that this adds to the interrupt latency.
Note that this patch breaks backward compatibility in terms of
setting up interrupt for UART controller. How to use UART is still
the same.
This also addresses the following issues:
() UART driver for Atmel SAM3 currently does not support interrupts.
So remove the code from vector table. This will be updated when
there is interrupt support for the driver.
() Corrected some config options for Stellaris UART driver.
This was tested with samples/shell on Arduino 101, and on QEMU
(Cortex-M3 and x86).

Due to a quirk of the k20 UART, when checking if either a Tx or Rx
irq is ready, one must first check whether the UART has enabled the
Tx and/or Rx interrupts. If this is not done, then all one is doing
is testing the UART to determine if it is ready to Tx and/or Rx.

This restructures the device structs and now utilizes the new
driver initialization model. This is another step towards
converting the serial driver to the new driver model.
Note that the serial driver does not initialize the hardware
unless it is being used by another driver. The configuration
of the serial port needs to be done by the driver utilizing
the port (e.g. baud rate, interrupt priority, etc.).
Therefore, some serial ports are declared but not exactly
configured.
Also note that the UART console is being initialized at
the same time as the serial port. This will be removed
in future patch, so the UART console driver will do
its own initialization.

UART on Quark platfor, according to Quark BSP Programmer's
Reference Manual, is located in the following order on PCI bus:
COM2 BAR0: 16550 registers
BAR1: DMA registers
COM1 BAR0: 16550 registers
BAR1: DMA registers
So, the driver on Quark platform has to specify BAR (Base
Address Registers) number, the pci_bus_scan() function looks for.
As long as UART is a concole device, calling pci_show() during
it's initialization does not make any output.
